Abstract

Coherent production of $K π$ systems observed in the excitation of 200-GeV/c positive kaons on nuclear targets has been analyzed, including both electromagnetic and strong contributions, to yield a new value for the radiative width for the process $K^{* +} (890) \to K^{+} γ$ of 51 ± 5 keV.
